When i installed the 315's on the back strange thing is happening. When i floor the car i dont hear anything scrubbing in the rear, but when the car jumps i do hear some scrubbing in the back. Why is that?

The suspension is not compressing far enough down during accelleration, but what you hit a bump the suspension is compressing more. The tire is either scrubbing the inner wheel well, or possibly the outer lip. Check the tire for any scrape on the edge of the tread, and the wheel well lip for missing paint. On the inner wheel well you'll see the undercoat worn off.
